Let me just cite Christopher Colemann at this point to tell you what we did there:

In late February 2016, a group of openFrameworks users and educators gathered in Denver Colorado to work on improving the ways people learn and use openFrameworks (OF). They worked intensely for 3.5 days, 12 hours per day, collectively committing more than 800 people-hours to creating and improving openFrameworks learning resources to help students around the world learn how to create with this powerful digital arts and design tool.
